An indicator (sometimes called a strike indicator or a bobber) is a floating tool you affix to your fishing line when fishing under the surface of the water with nymph flies. We field-tested and reviewed various strike indicators and weighed the pros and cons to help determine the best indicators for fishing your waters and season.

A nymph fly is a fly fishing lure designed to stay under the water, where fish do most of their eating. Since your nymph is under the water, it's hard to see whether you have a fish on your line.

The indicator acts as a floating visual aid alerting you to the possibility of a fish eating below surface.

When you see the strike indicator go under water, it can prompt you to set the hook and bring in a fish. 

In addition to the fishing applications of the indicators, we also looked at factors such as whether or not the indicator is biodegradable and made of sustainable materials since we believe in recreating responsibly and taking care of the waters we fish on. 

Adding an indicator to your nymph rig can often help you catch fish more successfully. Our goal is to help you find the right strike indicator for the waters you are fishing.

The Best Fishing Indicators

Oros strike indicators

Best Strike Indicator: OROS Strike Indicators 

Size options: 1.05", 0.85", 0.65"
Eco-notes: biodegradable foam
What we liked: well-balanced, design reduces splash and creates more natural looking drifts, fish less likely to be spooked, no tangle, secure, adjustable, biodegradable
What we didn't like: can be hard to find in stores, especially at smaller and rural fly shops

We think the Oros strike indicators are the best strike indicator for most anglers. The Oros is a bobber-style indicator that is centered on the line. An advantage of the Oros over other indicators is that it has no small pieces—just two halves that fit together. 

I've been using these relatively new Oros indicators for a year. They have been difficult to find as demand has outpaced production since they hit the market in 2020. 

They come in a couple of sizes, which is ideal for using the right size to fish different kinds of water. 

The Oros balances on the leader incredibly well since the leader passes through the indicator's center. So unlike other bobber-style indicators, it does not hang from the leader. This is useful for two reasons. 

Here's why bobbers that hang from the leader are a problem: First, they can create a splash when casting since they are heavier and their position below the leader. Second, they can also cause unnatural drifts as they create a drag point in the leader.

The Oros design, which passes through the leader through the indicator's center, reduces splash and creates more natural looking drifts. The Oros distributes its weight and mass evenly on the leader. That means fish are less likely to be spooked by unnatural splashing and drifting in the water.

PROS OF THE OROS STRIKE INDICATOR:

  • Balance: The balance on the Oros indicator is outstanding as the weight is evenly distributed on the leader, which means significantly less impact on your cast.

  • Lightweight: The Oros indicators are extremely lightweight even in their large size, making them easy to cast and land on the water much softer than most other bobber-style indicators.

  • Easy to attach and reposition as water depth changes. 

  • Incredibly secure on your leader. It locks down tightly and does not slide unintentionally.

  • Biodegradable to protect the environment if it is ever lost.

  • Very durable compared to other indicators. You’ll lose it before it ever wears out.

  • Sensitivity to strikes is excellent. I would again attribute this to the leader going right through the center of it.

  • Completely kinkless. It will not damage your leader even when screwed down very tightly.

  • No tangle. No posts or other catch points are sticking off the indicator to get tangled on.

  • Mix and match colors. Since there are two halves, the angler can mix and match colors.  Some anglers believe that colored strike indicators can spook fish especially if the water is exceptionally clear. Oros enables the angler to put a white halve of an indicator on the bottom side of the leader that will float in the water and will be the side the fish see. Then the angler can use a more brightly colored halve on top of the white to make the indicator more easily visible over an all white indicator. The reason is that some anglers (not me) think colorful indicators can spook fish. But all white indicators can be hard to see. So since there are two halves in theory you could put a white half on the bottom that would be the halve the fish would see looking up and a colored halve on top for the angler to see more easily.

Some anglers (not me) believe that colored strike indicators can spook fish, especially if the water is exceptionally clear. Oros enables the angler to put a white halve of an indicator on the bottom side of the leader on the side the fish see.

CONS OF THE OROS STRIKE INDICATOR:

  • As a new company, Oros is still working on distribution. Don't expect to find them in every shop or in remote locations — yet. 

  • Risk of dropping half of the indicator, rendering it useless. The indicator splits into two pieces, so there is a lot of risk of dropping a half while attaching or removing it. Without both halves, the indicator is useless.

  • Grip. While the biodegradable foam is soft and lightweight, it can be challenging to get a grip on to unscrew the halves, especially when wet.

  • Not as buoyant. Not as buoyant as some other bobber-style indicators and can be pulled underwater with heavier flies or weight added.

  • You cannot run a 90-degree rig without adding a swivel or tippet ring.   


Air Lock Strike Indicators

Best Widely Available Indicator: AIRLOCK Strike Indicators 

Size options: 1", 3/4", 1/2" 
Eco-notes: biodegradable foam
What we liked: secure, adjustable, biodegradable, can be attached to 90-degree rigs, easy to find
What we didn't like: easy to drop pieces, line kink, less sensitive to subtle strikes

If you ask someone for an indicator, chances are they’ll hand you an Airlock or Thingamabobber. Grab the Airlock if you can. I have fished with Air Lock Strike Indicators for years. I like them because they are incredibly effective and can be used in many applications, thanks to easy adjustability and 3 different sizing options available. The Airlock Strike Indicator is biodegradable, but also very buoyant and can handle heavier flies. Airlocks are widely available, much more so than the Oros. You don't need to go to specialty fly shops to get them.

What makes the Airlock such an effective indicator is that it allows for a 90-degree rig. In fact, to my knowledge, the Airlock is the only indicator currently on the market that allows for 90-degree rigs. 

A 90-degree rig is where the end of your leader, tippet, and flies hang straight down in the water from the indicator. Some anglers—including our tester—find that having a 90-degree rig creates a better presentation for the fish. It also makes the indicator more sensitive and responsive to takes from fish. 

The Airlock packing comes with an illustration with instructions describing how to set up a 90-degree rig using the indicator, which is very helpful. Here is a link to the Airlock website and if you scroll to the bottom of the page there is an illustration of how to set up a 90-degree rig using their bobber.

PROS OF THE AIR LOCK INDICATOR:

  • Thanks to the screw-down top, it fastens very securely to your leader and does not move even in swift river conditions.

  • Easily adjustable. To change the indicator's position on your leader, loosen the screw top and slide the indicator to the desired position.

  • Very buoyant. The foam body floats extremely well and can handle quite a bit of weight from flies with heavy bead heads or from additional weight placed on your tippet to sink the flies.

  • Biodegradable over time when left in the elements. You don’t have to worry about polluting the waterway if you lose one.

  • It allows for 90-degree rigs. Some anglers—including our tester—find that having a 90-degree rig creates a better presentation for the fish. It also makes the indicator more sensitive and responsive to takes from fish.

Here, the bright pink is clearly visible against a bright overcast sky, which may improve visibility comparing to white indicators in the same conditions. Photo by Bri Dostie.

CONS OF THE AIRLOCK INDICATOR:

  • It has several small, easy-to-drop pieces. You can easily drop the washer and screw top. Without them, the indicator is useless. Airlock includes extra tops in each 3 pack of indicators, and you can purchase extra tops from the company, but this is still a significant negative since you cannot use the indicator if you don’t have a spare top.

  • Line kink. While the company says that the indicators are kinkless, we found that if the top is tightened fairly tight, it will still put a bit of a twist or curve in your leader where it was positioned after you remove your indicator (especially when using it for 90-degree rigging).

  • Can be less sensitive to subtle strikes. Due to the buoyancy of the indicator, it can tend not to be as sensitive to subtle strikes as other indicators. This is because it requires a little more force to pull the indicator down into the water. The angler must be alert for small changes in direction and set the hook, which results in more false hooksets.

  • Attaches at the top. Since this indicator attaches at the top and essentially hangs from your leader, it can impact your cast's accuracy. The design also means it can quickly become a tangle point for your flies and tippet to get wrapped on. The top attachment can also cause the indicator to not land softly on the water while casting and disturb or scare fish.


New Zealand Strike indicator

Best for Spooky Water: New Zealand STRIKE INDICATOR

Size options: Trim to size
Eco-notes:
made of wool
What we liked: very effective for subtle presentation on gin clear water, can control float you need, made of sustainable material, biodegradable
What we didn't like: learning curve, not the best for fast and rough water, small pieces can be tricky to care for

The New Zealand Strike indicator is a highly customizable, biodegradable indicator made of natural materials. You apply a custom amount of sheep wool each time, so you can control the float you need. We think the New Zealand Strike Indicator is the best indicator for fishing gin clear or spooky water. We also think that it is the most eco-friendly indicator because it is made of a sustainable, biodegradable material. However, there is a learning curve to get the right balance for the run you are fishing.

COMPARE PRICES OF THE NEW ZEALAND STRIKE INDICATOR

PROS OF THE NZ STRIKE INDICATOR:

  • Natural, biodegradable fiber. We appreciate the fiber is from happy sheep on a happy farm in New Zealand.

  • Lightweight, simple casting. Casting is simple and no more cumbersome than other strike indicators. In fact, some anglers find that casting is possibly improved when using the NZ wool indicator, given how light the materials are. 

  • Very effective for subtle presentation on spooky water. Unlike larger, solid-formed indicators, the NZ Strike Indicator system uses natural sheep fibers which are more easily mistaken for organic debris that naturally appears in a water ecosystem. While a bright circle on the water’s surface doesn’t typically have look-alikes, a tuft of wool can disguise as leaf litter, pollen or other plant fibers, or even a hatching fly. Additionally, by having control over the amount of fibers used, an angler can pare down on indicator size if a larger floof causes too much commotion on the surface.

CONS OF THE NZ STRIKE INDICATOR:

  • Tiny silicone tubes and applicators can be tricky to care for and maintain: After a season's use (and not drying out the contents of a fishing bag appropriately over the season), we had a rusted hook and broken applicator. The company replaced this for us. Here's a link to the company's care and maintenance section

  • Must dry out indicator. Being a natural fiber, these are going to face the struggle of floating over a long time, meaning it will be necessary to dry out the indicator or add new sheep fluff from time to time. If fish are eating subsurface, you need a lot of fluff. 

  • Some kinks. Like other strike indicators with a line cinch attachment, this creates kinks in your line over time. 

  • Not the best for rougher, faster-moving water as they will more quickly get soaked and sink below the surface.


Corqs indicator

Best for Indicator for Beginners: CORQS 

Size options: 3/8", 1/2", 5/8", 3/4", 1"
Eco-notes: made of cork
What we liked: secure placement, excellent for stillwater, biodegradable materials, approachable and easy to use, can be used on a variety of water, designed so you’re less likely to lose it
What we didn't like: some learning curve for application, can lose rubber loops

The CorQs indicator has a traditional bobber design but has design and material improvements over old-style bobbers that make it better for beginners. Its design is more approachable and intuitive than traditional bobbers, so beginners can get the hang of it more quickly. Second, it uses more sustainable materials than old style indicators. 

The CorQs is an excellent indicator for beginners because it is easy to attach to your leader and is designed to point towards your subsurface flies. The CorQs has a decent float and a full suite of standard size options, so it has wide application across varying water conditions. Its eco-friendly materials make it a more natural presence on the surface of the water than old-style bobbers. While it still has rubber material for loop attachment to the line, which means it isn't 100% eco-friendly, it’s easier to attach than old-style indicators which means you're less likely to lose it.

PROS OF THE CORQ INDICATOR:

  • An excellent standard grab-and-go option 

  • Many sizes

  • Straightforward application to line

  • The rubber loop helps keep the bobber in one place on the line. Without some kind of traction with the very slippery leader or tippet, an indicator will migrate towards the end of your line as you cast and move your flies around, and can more easily cause tangles casting. Having a rubber loop adds at least a little more security for your indicator placement staying put, therefore allowing for consistent weight distribution in your cast. While not foolproof, the loop keeps things more or less in static position.

  • Excellent for still water. the rubber stoppers can be removed so the indicator can slide intentionally, allowing for easier casts. With slow sinking flies, the indicator will settle at the actual surface line of the water while allowing flies to sink to their maximum depth. Unlike other indicators, it won’t interrupt the descent by suspending flies at a fixed depth. The stoppers are small enough to still feed through eyelets/guides on the rod, so helpful when reeling in lots of line and maintaining tension when landing a fish.

  • Rubber stoppers are shaped to point to your subsurface line/flies. They are helpful in understanding where your flies are below the surface: the oblong shape points to your subsurface line/flies, unlike traditional circular bobber shapes. 

CONS OF THE CORQ INDICATOR:

  • No kink in line: most indicators are attached by cinching to your leader, and the material of the leader does have memory. Over time, this can result in compromised fly fishing gear and expedite replacement. When testing this model of indicator, kinks in the line were quite limited!

  • Learning curve: the leader application is more specific and complicated than other options. That means more work up front for a flexible indicator option. This pre-rigging application process requires an indicator to be attached to a clean leader (meaning a leader without tippet extensions/associated knots)

  • Rubber loops slip after prolonged use, so you will likely need to reposition your indicator from time to time

  • The tiny rubber stoppers are easy to lose. The Corq is not immune to the shortfalls of other rubber loop stoppers on bobber-style indicators of slipping once wet.

Honorable Mentions

poly yarn fly fishing indicators

Poly yarn

Size options: n/a

Eco-notes: not biodegradable

Poly yarn is essentially a bit of fluff on the water's surface. It functions like a dry fly without a hook. Poly Yarn's benefit is that it has a more subtle presentation on the surface of the water than other indicators, which can be good for spooky fish.

However, like other yarn indicators, it is prone to becoming submerged with too much weight or prolonged use. While this type of indicator can be a favorite for some anglers, we prefer the flexibility of sizing up or down with the NZ Strike Indicator system, and prefer the all natural fiber source compared to synthetic materials typically used in these yarn options.

Loon Outdoors Strike Two

Size options: n/a

Eco notes: reusable putty

The Loon Strike Two indicator is like a bridge between the yarn pre-tied types of indicators and the NZ style indicator.

It's easier to cast than many bobber-style indicators.

It also has a more subtle presentation on the surface of the water than many indicators. However, it requires a flotant (as you would add to a dry fly) to move in the water. In our testing, once the yarn becomes saturated after extended use, you might as well just use the dry fly.

Westwater THINGAMABOBBER

Size options: 1/2", 1", 1.25"

Eco-notes: plastic

The Thingamabobber is a classic indicator. It's durable. However, it's made of plastic and is not sustainable compared to other indicators on the market now. It is a very accessible option. You can find it in almost any fly shop or outdoor chain store. 

Thingamabobbers are an affordable indicator that is widely available, but found it has some frustrations and is made of plastic.

Not much has changed with these classic Thingamabobber indicators, which are consistently available at larger department and sporting good stores as well as fly shops. Photo by Bri Dostie.

In our opinion, the Thingmabobber is a standard that has needed updates for a long time. We like that it’s accessible for trying out indicator nymphing due to availability and its price. But we have qualms with it. 

Functionally, it slides down your line after casting—and that happens pretty quickly. We also find that subtle takes are sometimes lost on larger sizes of fish. 

While the Thingmabobber is an effective option, it has a few added frustrations that new indicators, like the CorQs, have fixed. Also, we prefer an indicator that isn't made of plastic.

Wapsi Fly Palsa Strike Indicator with Pinch on Floats

Wapsi Fly PALSA Strike Indicator Pinch On Floats 

Size options: n/a

Eco-notes: foam with fabric

The Wapsi Fly Palsa Strike Indicator with Pinch on Floats is made of felt material with an adhesive. We found the adhesive can gunk up your line.

It's also not as easy to adjust the depth of your nymphs aside from tying on more tippets or prying the indicator off and replacing it. However, we found the smaller size makes for easier casting with fewer tangles.

Palsa stick-on strike indicators use adhesives that can sometimes cause issues on a line.

Stick on indicators like the Palsa make sure your placement stays put, losing the flexibility of adjusting depth in ways other indicators allow for. These indicators are great for fixed location and depth, though may have you tying more length with tippet if you plan to cover a lot of varying water in a day of fishing. Photo by Bri Dostie.

A large dry fly like this can be used instead of an indicator to suspend a nymph pattern below, tied on either the eyelet or back hook of the fly to dangle in the subsurface current. This is called a dry-dropper set up, and can be an effective approach to fishing when large bugs are present as well as aquatic nymphs. Photo by Bri Dostie.

DRY FLY

If you don't want to use an indicator, you can always use a dry fly to drop submerged fly patterns from. This approach is called a dry dropper, and is very popular as it increases options for how to entice a fish to eat by fishing both on the surface and subsurface at the same time.

What is nymphing?

Nymphing refers to a type of fly fishing where your flies are floated down the river or in the still water at different columns (depths) of water.

When nymph fishing, you decide the depths of water you are fishing so they correspond to where the bugs can be found in the water that make up a fish’s diet.

Bugs live at different depths depending on their life cycle, so anglers will match the depth of water they fish based on bug life cycles.

The vast majority of a fish’s food is consumed under the surface. While fish will feed on the water's surface during specific fly hatches at specific times of the year, the most effective way to catch fish is using nymphs under the water. 

Nymphs are a type of fly fishing lure designed to stay under the surface of the water. It has a tungsten bead to weigh them down and prevent them from floating. An indicator can make catching fish while nymphing easier.

How do indicators work?

An indicator is used to provide a visual feedback point to an angler when the flies themselves are not visible, which is often the case while fishing nymph flies. While you can fish nymphs without an indicator, it can be difficult to tell when a fish has subtly taken your fly and requires the angler to feel for a take just using their fly line.

Often a fish will take your fly and release it without the angler knowing anything happened, simply because of how subtle fish can be while eating subsurface. An indicator provides a more obvious signal when a fish has your fly, typically by stopping in the current or being tugged under the surface of the water, signaling that the fly is no longer moving with the current and is hopefully in a fish’s mouth.

How do you set up a nymphing rig with an indicator? 

Determining where to attach an indicator depends on the depth you wish to fish your flies below the surface of the water.

Once you have selected the fly or flies you want to use and have a sense of where those flies need to be in the water column, you measure out the depth from your flies to the appropriate length of tippet and/or leader segments.

A second smaller fly that imitates a midge is tied on with tippet to the hook of the lead fly, and fishes along the bottom with a few inches of tippet separating them. Photo by Bri Dostie.

The indicator will float on the surface. Everything below the point where it attaches to your leader will hang below the surface.Guessing the depth from surface to riverbed or bottom of whatever water you are fishing involves a fair amount of trial and error; if you can’t see the bottom, you can roughly measure using a nearby stick, or make your best guess when first attaching your indicator and plan to adjust from there. 

The indicator will float your flies at a fixed height in the water column or allow them to bounce along the bottom of the water if you are fishing flies found on the bottom.

Recognizing how currents in the water will impact your fly movement is also important, as a strong current may require longer segments of tippet or leader than still water of the same depth. These factors can be mitigated by incorporating weight, such as bead-headed flies, split shot, or other weights attached to your leader and tippet.

Some indicators are better than others at handling the weight of flies and keeping them afloat. Some aren’t capable of handling much weight and can only be used with very light flies. Some can't handle much weight and can only be used with flies being fished on the bottom of the water column. If a fly is too heavy for its indicator, the fly may pull the indicator down prematurely before you have a fish.  

The type of flies you will be fishing and how much weight you choose on your leader/tippet will often determine the indicator you need. 

We recognize you're likely to fish in a wide range of situations, so we field-tested and reviewed a variety of indicators to help make determining the right one for your situation a little easier.

Buying Advice

Here is what we looked for in an indicator. 

Function:

To find the best fishing indicators, we evaluated bobbers on whether they do what they are supposed to do: 

  1. To what extent does it stay above water? 

  2. How much does it move when a fly is eaten?

  3. Does it cast reasonably?

  4. Will it last over many uses?

Sensitivity in varied conditions: 

Can it handle fast-moving current? Still water? Clear water? 

Castable ergonomics: 

We prefer bobbers with a light, unobtrusive design. There are several ways bobbers can do this: 

How it casts and presentation:

Fiber, wool, and yarn-based indicators cast more like a fly, which is beneficial for casting farther and avoiding tangles. These types of bobbers have a more subtle presentation and better line management on the water’s surface. 

In contrast, bobber-style indicators tend to create disturbance or splash on the water's surface when you present your fly, which can sometimes mean spooking the hole or certain fish. 

Functionality: 

To determine the functionality of an indicator, we judged based on whether the indicator suspends successfully on the surface of the water.

Nymphs are weighted and intended to be fished at or near the bottom of the river. Indicators need to be able to suspend line and pull subsurface only when a fish eats (or the rig snags).

Bobber-style indicators tend to be able to support more weight below the surface. Fiber, wool, and yarn-based indicators can't handle as much weight and may require floatant to stay on the surface. Sometimes, they simply cannot support heavy flies effectively.

Sustainable materials: 

It's important to take care of the waters we fish on. That is why we preferred indicators that are biodegradable and those made of sustainable materials.

Our goal is to get away from indicators and bobbers made of foams and plastics. There are many foam strike indicators that are still on the market. There are also many plastic options or other artificial materials like putties that do not biodegrade.

However, now there are more compostable and natural material options on the market. It's not possible to get a foam indicator that will biodegrade if it is lost. We focus on more sustainable options in this review.

OTHER FLY FISHING TOOLS YOU MAY NEED:

It's always worth checking the fishing report for the waters and time you are fishing. 

Weight: 

When not using flies that already have a heavy bead or wrapped weight, you may want to add some weight. Adding weight directly to the tippet can get your flies to where they need to be in the water column to mimic the life cycle of bugs your fish are eating. 

Two examples of weight are Split Shot and tungsten putty. 

Split shot is a reasonably accessible option in most outdoor stores. Here is a split shot option from Orvis that we like due to its environmentally friendly and non-toxic design. 

Tungsten putty is a bit newer type of weight. It has the benefit of being able to wrap this heavy silly putty along the line rather than in one blob. This is much easier to cast as you are less likely to have weights tangle with dangling flies. There is some putty on the market that is not as eco-friendly. Here is an option from Loon Outdoors we like due to it being biodegradable. 

Floatant: 

Floatant is important if you are using natural fiber or yarn indicators because they can become waterlogged very easily and will no longer float on the surface without assistance. Using a as a pretreatment for your yarn indicator helps improve water repelling and buoyancy. We like Loon Outdoors Aquel gel floatants as these are water soluble and solvent free, best for delicate ecosystems. Just apply and let it air dry before you start fishing. 

Tie on strike indicator: 

If you are curious about tight line or euro nymphing (two styles of fly fishing that are becoming more popular), it's typical for anglers to add a two-color indicator segment of the line when building a euro nymphing leader. Here is an offering from RIO that comes in a few different color schemes. 

Net: 

A net is always helpful for fish handling and landing fish once they’re hooked. We recommend reading about improving the outcome for your fish at Keep Fish Wet. The net also means the fish has less opportunity to break the line and abscond with your fly and hook. Plus, a net gives you more flexibility for taking a picture with your catch. I use an inexpensive net from Amazon that folds down for easy travel and packing.  

Fly box: 

Nymphs come in all shapes and sizes and you’re going to want to have a lot of options available to you while fishing so that you can try and match the bug life in the water you are fishing. A good fly box will be able to carry all the flies you might need, and help keep them organized so that you can easily find the fly you need. Fly boxes come in a wide variety of sizes, and for nymphing you frankly can’t have too many options of flies available to choose from. We recommend a large fly box like this Tactical Max Box from Fulling Mill.

I’m Bri Dostie, coming to this article from the home waters of the Wabanaki confederacy in Maine, which range from still water ponds to massive rivers, from saltwater flats to spring-fed mountain brooks. I’ve been fortunate to fish beyond local spots as well and meet a diverse cast of fish species on my adventures through the western United States, Alaska, and the lakes region of Chile. I’m a Maine Fishing Guide who teaches primarily beginner anglers—which informs my use of gear and keeps the frustrations and challenges of getting started in the sport at the top of my mind. I’m also the founder of Confluence Collective, a community where every body belongs on the water.

I’m coming to this sport having used hand-me-down gear built by and for people who don’t look like me. Now, because of my job as a guide, I have access to countless rigs at fly fishing expos and shows—events that bring anglers and manufacturers together to show off the latest gear and try it out on casting ponds. These shows aren't very accessible, but with my privilege as a white, cis-gendered, industry insider, I'm more easily able to navigate these white- and male-dominated spaces. (And I can always throw on a plaid shirt and trucker hat to reinforce my perceived belonging.) BIPOC and LGBTQIA2S+ anglers are often othered at these events, and there's a lot of work still to do to remind the white angling community that they're not the only ones on the water. This article is aimed at reducing gatekeeping in fly fishing.

Cade Kloberdanz is a lifelong fly fishing angler with a passion for conservation and disabled access to the outdoors for all. He was a panelist on How to Get Started Fly Fishing and is an active member of Confluence Collective focusing on disabled access projects and social initiatives. 

As a paraplegic himself, Cade is intimately familiar with the difficulties faced by individuals with physical disabilities in accessing the outdoors in general, and specifically when it comes to access for fishing. 

In his own personal experience, he has found that true access for disabled people to the water is often inadequate or nonexistent, especially when it comes to rivers and streams. 

Since becoming paralyzed in 2018, he has dedicated himself to championing causes that provide access to the water for individuals like himself. He has worked extensively with groups like Project Healing Waters Fly Fishing teaching other disabled veterans how to fly fish, tie flies, and build rods. 

He's the President of the Grand Valley Anglers Chapter of Trouts Unlimited and on the Equity Working Group for Colorado Trout Unlimited. ⁠You can follow him on Instagram at @how_now_brown_trout.
